If you're wondering where Rock Band 3 is, a year and a half after Rock Band 2 and five months after the launch of The Beatles: Rock Band, it seems EA isn't sure it's going to get to publish it. During an investor conference call, EA execs revealed that the publisher's deal with Viacom (the company that owns MTV, Harmonix, Rock Band and maybe you as well) is only active through fiscal year 2010 (which ends March 31).

Presumably the deal somehow includes the yet-to-be-released Green Day: Rock Band -- but EA's unlikely to announce any more Rock Band games until it knows it has the license locked down for another year.

[Update: An MTV/Harmonix spokesperson has told us "The previously announced Green Day: Rock Band will be published by MTV Games and distributed by EA. Stay tuned for news of MTV Games' other titles soon."]
